Statue Of Liberty- 23 Statue of Zeus - 8 Stonehenge- 21 Sydney Opera House- 18 Taj Mahal- 4 It's just a golden age Temple of Artemis - 21 Uffizi - 20 Brandenburg Gate - it's one I'll always look to snatch if planing on warmongering. This + other XP buildings makes your unit incredibly powerful right from the start (bombers with air repair and few shoots from logistics) Statue of Zeus - requires Honor which and comes too early in the game to be really useful. Extra damage to cities won't really matter when your units deal small damage, and it's bonus damage is easily replaced with few extra units that cost less hammers and less time to build. other honorable mentions are Kremlin and Taj Mahal. Golden Age and Social Policy are easily gained, so it's not that impressive and if you're playing Order, you probably already have a chance to crank up dozens of tanks anyway.
